22th December 2009 Etching tip solution of 7 g CaCl2·2H2O in 40 ml H2O and 2 ml acetone. An ac voltage of 7 V at 700 Hz was applied between the wire and the smail pt(?) ring (as you did for etching W tip)around it . The voltage was applied until the wire fell apart . LEED Spectrum Transfer Hook ! it is a temporary solution Dismount Almost broken-the reactor New design: bellow flange with a CF connection New bellow flange New sample holder holder No way to rotate! Reactor! alignment: height done capillaries done copper ring not yet To do..... alignment ..... back to UHV..... Bake-out...... Thanks a lot ! * * * * * * * * * * * * * * * * * * * * * *
